DERAILINGQ-SWITCH.

SPECIFICATION forming part of Letters Patent No. 474,976, dated May 17,1892. Application filed December 21, 1891. serial No. 415,736. (Nomodel.)

To all whom it may concern.-

Be it known that I, AXEL A. STROM, a citizen of the United States,residing at Austin, in the county of Oook'and State of Illinois, haveinvented a new and useful Improvement in Derailing-Switches, of whichthe following is a specification. 7

The object of my invention is to provide an improved construction ofswitch whereby when the main-track switch is setfor the main line theoperation of so setting it will open the side-track switch, and therebyinsure derailment of a car or train on its way to the main line from thesiding.

My invention consists in peculiar details of construction andcombinations of parts, all as hereinafter described, and set forth inthe claims.

The accompanying drawing represents by a plan View a section of arailroad-track pro- Vided with my improved derailing-switch apparatus.

A denotes the main line, and B the siding.

Where the transfer-rails t and 25 from the side track meet the rails ofthe main line,I provide the two movable point-rails of a split switch G.At the end of the siding transfer-rail 25, adjacent to the rail o of thesiding B, I provide a movable point-rail O, and for a purposehereinafter explained the end of the rail v should be deflected outward,as shown at 00.

F is a switch-operating appliance of any suitable form and construction,the switch-rod 'r of which is connected in a usual or suitable mannerwith the split switch Gto throw both point-rails p simultaneously byoperating the appliance F. Beyond the main line A, at the side thereofopposite that at which the appliance F is situated, is a T-shaped ordouble bell-crank lever D, linked from its arm 8 to the split switch G,(as to the connecting-rod r, if, as shown, the latter be used to connectthe rails 19.) From the ends of its arms 3 the lever D is connected bymeans of wires to with the corresponding arms 5 of a lever D, like thelever D, and having its stem-arm 8 connected by a rod r with thepoint-rail O, In the connecting mediumw between the levers D and D,which may be wires, cables, or rods, I provide turnbuckle devices q for1tially as and for the purpose set forth.

maintaining taut the connection. As represented in the drawing, thesplit switch G is set for the main line A, having been thrown 'to thatposition by manipulating the appliof opening the side track B. If then acar or I train on the side track were to move to the bent end 00 of therailo, it would be prevented from reaching the transfer-rails t t,andthence the main line by derailment, and the advantage afiorded by thedeflected end'oc of the siding-rail o is that the point-rail O, which isfirmly stopped by chairs, braces or other stops 0 at the end of itsthrow, guides the car or train past the connecting-rod r, and producesthe derailment beyond it, whereby it will not be broken or damaged bythe occurrence.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a derailing-switch, the combination, with the main line A, sidetrack B, and transfer-rails t t, of a split switch G between the railsof the main line, a deflected extension 00 at the end of the siding-rail'v, a movable point-rail O,-extending from the rail 25 to the extension00 and connected with the switch G, to be operated by throwing thelatter, and a switch-operating appliance connected with the said splitswitch, substantially as and for the purpose set forth.

2. In a derailing-switch, the combination, with the main line A, sidetrack B, and transfer-rails t t, of a split switch G between the railsof the main line, a deflected extension at at the end of the sidingrail2;, a movable point-rail O, extending from the rail t to the extension00 and connected with the switch G to be operated by throwing thelatter, arigid stop 0 at the end of the inner throw of the point-rail O,and a switch-operating appliance connected with the said split switch,substan- 5 3.
